WILLIAM L. M. JONES, or WINNIPEG, MANITOBA, CANADA p HARVESTING MACHINE if Application filed July'3, 1931, Serial No. 548,572, andin can aa m 2, 1931.

The invention relates to improvements in harvesting machines and an object of the invention is to providea harvesting machine which will build the cut-grain delivered thereto into a stack and deposit the stack firmly planted on the ground in an upstanding position, the machine being entirely under the control ofa single operator attending it.

A further object of the invention is to pro- '10 vide, a machine which will build acircular stack having the heads of the grain at the centre and the butts at the outer side and will also give the stack a cone shaped top and pack the grain as the stackis being' built to give a relatively firm stack. h

A still further object of the invention is to provide a means which will tuck the outer side of the stack as it is being built and thereby interknitting the butt ends of thegrain so that the side of the stack is firm and will resist wind. 7 1 e A still further object of the invention is to provide a machine wherein the stack is built by feeding the grain in a special manner through the open top of a cylindrical container having a rotating tableclosing the bottom thereof, such resulting in the grain being built up in a spiralling manner within the container to form a stack with the heads thereof centrally ofthe stack and the butts out.

A further object of the inventionis to provide the table with cleats orsuch like members insuring of the turning of the grain'with the table and means for initially raising the container to clear the cleats prior to the container being moved back to deposit thestack.

- A further object of the: invention is to provide a container which after the stack has been built 'canbemoved re'arwardlyto de- 40 posit the stack on the ground and to associate with the container, gates automatically opened to permit the stack to clear the machine, such gates being also automatically closed and without slamming as the container moves back to its initial receiving position.

. A still further object is to provide means to eiiectively hold the lower inner corners of the gatesclosed during the time that-the stack is being built and for a short period after the container has started its rear movement.

A still -further object of the invention-is to .provide opposing spaced rackbars extending, centrally forwardly from the container anda driven gear which can be engaged with one or other of therackbars by. the attendant to effect the 'rear or forward movement of the container and to arrange the rack bars in respect to the gear that when the container has reached its rear-or forward position, it

will automatically stop, due to the gear running off the-end of the rack bar at which time the other rack bar underlies or overlies, as the case may be, thegear.

A still further object of he invention is to provide means whereby the'table is automatically stopped rotating when the container starts its rear movement and means whereby the packer and tucker utilized will also be automatically thrown outof commission when the container starts to move rearwardly and to arrange parts such that when the container has resumed its original position, thetable packer and tuckerwill be operated. I V o A further object of the invention is to provide a packer for the top and a tucker for the side of the stack being built in the container .which will move with the container when the same is depositing thestack and will not be driven during such time and to provide means for automatically driving the packer and tucker when the container resumes its normal forward position.

1 With the above more important and other minor objects in viewwhich will become more apparent as the description proceeds, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawings, in which o o Fig. 1 is a front view of the machine, the stub tongue being shown in vertical section.

Fig. 14: is an enlarged detailed horizontal sectional view at 1l14; Figure 7 In the drawings like characters of reference indicate corresponding parts in the several figures;

The machine embodies a main frame 1, the details of which are best shown in Figure 5. The main frame is supported at one side by a bull or master wheel 2 and at the other side by a ground wheel 3, the wheels being carried by shafts l and 5 suitably mounted in bear ings carried by the main frame. It will be observed that the sides of the main frame are made particularly strong by effectively bracing.

Associated with the bull wheel, I provide atthe inner side a relatively large chain wheel 6 andat the outer side a considerably smaller chain wheel '7, the chain wheel 6 being connected by a chain 8 to a chain wheel 9 mounted on a forward cross shaft 10. The chain wheel 9 is rotatably mounted on the cross shaft anu is controlled by engageable male and female clutch members of well known design and indicated generally by the reference numeral 11, the arrangement being such that when the clutch members are en gaged, the chain wheel rotates the shaft and when disengaged, the chain wheel rotates freely on the shaft.

The movable clutch member is controlled by a rocker arm 12 pivotally attached to the machine frame and having the u 3per end connected by an operating bar 12 to the forwardly cranked end of a rod 13 rotatably carried by the machine frame and passing horizontally rearwardly and terminating in a hand lever 13' within convenient range of the drivers platform 1 which latter is provided with a seat 15. That part of the main frame between the wheels carries a pair of cross bars 16 and 16 which support more or less centrally of their length a plate 17 which is provided with an upstanding pivot pin 17. v V

This pin forms a central pivot point for a circular table 18 which is adapted to re volve in the lowermost part of the frame, the rear edges of the table being supported by rollers 19 carried by a rearward frame cross bar 19 and the forward side of the table being carried by a pinion 20 which engages continuously with a circular rack bar 20 fastened to the under side of the table adjacent the edge thereof. 7 A roller 21 rides the top of the table in a location adjoining the pinion, such roller insuring of the rack bar and pinion being maintained positively in mesh.

The pinion 20 is carried by the rear end of ashort shaft 22 rotatably carried by the forward part of the frame and the shaft is supplied with a chain wheel 22 connected by a chain 22 to a chain wheel 23 mounted on a countershaft 23 rotatably carried by the frame and provided at its forward end with a bevel pinion 24- which meshes continuously with a bevel gear 24 rotatably mounted on the shaft 10. A clutch indicated generally by the reference numeral 25 is associated with the bevel gear and the shaft 10, one of the clutch members being driven by and slidably mounted on the shaft and controlled by a link 25 pivotally connected to a bell crank 25 carried by the frame. A pulling bar 26 is also connected to the bell crank and extends vertically upwardly and has the upper end thereof pivotally connected to a crank 27 extending forwardly from an elevated cross shaft 27 carried by the fore part of the frame structure. One end of the latter shaft is supplied with a crank 28 which is connected pivotally to an operating bar 28, the rear end of which is pivotally at tached to a manipulating lever 29 pivotally carried by the rear part of the frame in a location adjoining the operators seat.

According to this arrangement, the operator by manipulating the lever 29 can engage or disengage the clutch 25 and in so doing effect the rotation or stopping of the table. The table is provided at the upper face with a number of radially disposed cleats 18 herein shown as angle bars.

Above the table is a cylindrical casing which is indicated generally by the reference numeral 30 and this casing is carried by the frame and is adapted to move forwardly and rearwardly thereon and in its forward position forms with the table a grain receiving container in which stacks are built in a manner fully described hereinafter.

The container comprises a forward vertically disposed and suitably braced semi-cylindrical body 31, the rear part of which is normally closed by rear gates 32 and 33, one of which is shown in detail in Figure 7. It will be observed by reference to this figure that the gate is formed from vertically disposed angle bars 34 and 34' which are connected b spaced upper, lower and intermediate bowed bars 34* to which bars, the closureplate'35 is riveted. Thebalrs 34' are approximately the same height as the body part 31 ofthe container while the bars 34;are somewhat higher than the containerand are pivotally connected by'hinges 36', in'each instance to the'rear vertically disposed bars 37' of asuitably braced framework 37reinforcing the fore part31 ofthe container; u

Thisframe Work .sutilized also to support the driving mechanism of apaoker38 and a tucker39'associated with the container and the details of which will be later described. Thebars 37 extend above the body part 31 of the container and are effectively braced to the frame work as indicated at 40 and the upper enc sof'the bars 34 are connected by angularly disposed tie rods 41 centrally to the uppermost bars 34*, such avoiding sagging of the-gates.

The gates are also reinforced bycrossed tie rods 42 passing diagonally across the same from ,corner'to corner at the exterior. The cylindrical container is supported centrally at the sides by rollers 43 and 43 which operate on rearwardly extending elevated horizontally disposed opposing tracks 44 and 44carried by the main frame and it will be observed that the rear ends of these tracks extend rearwardly a considerable distance to the rear of the main frame,-the .rear ends thereof being; suitably supported by angle braces 45. 1

The front ends of the tracks are designed to support the cylindrical container with the lower end thereof just nicely clear of they table and the tracks are provided with slight offsets 46 designedin the initial rear movement of the container to bodily lift the same so that the lower end thereof can clear over the cleats 18' of the table. Once the container has been so lifted, it moves horizontally rearwardly on the rear portions of the tracks and its rear travel is such that any stack built in the container will be cleared oil the rear side of the table. The container is positively pushed rearwardly and pulled forwardly on the tracks, the time of starting the forward and backward movement being controlled by the attendant but the stopping of the forward and backward movement being automatic. The controllingmechanism will be later described in detail.

Means is provided for reinforcing the lower inner corners of the, gates as the container is moving rearwardly and such embodies a somewhat V-shaped pressure bar 47 secured to thelower part of each gate and arranged to engage with a guide bar 48 permanently secured to the rear part of the frame.

Obviously these V-shaped pressure bars 47 will take any undue strain brought on the lower inner corners of the gates at the time the container is moving backwardlyand will serve to reinforce the lower inner corners of the gatesluntil suchtime that the said bars stack has been deposited and during the forward movement of the container. Such embodies a horizontal lever 49 pivotally attached more or less centrally to the hinged side of the gate and having the rear end thereof pointed and provfded, adjoiningthe point with a suitable stop 49. I A spring '50 is interposedbetween the inner side of the leverand the ate and in the closed position of the gates, t ezrear ends of the lovers are engagedwith thexinner faces of the tracks 44 and 44 which they ride in the back going movement ofthe container and normally the spr ngs 50 arecompressed so that they are acting to force the gates closed. The spring is mounted, on a rod 50 having one end piv otally attached to the lever 49 and the other end passing 7 slidably through an angle bracket 50* secured tov the adjacent gate and having the extremity thereofterminating in an enlarged head 50 e Rearwardly each of the tr'aclzs is provided with means for catching the rear pointed end of the lever 49 held by that tracl-z and such embodies a horizontally disposed arm 51 having the outer end thereofpivotally con.-

nected at 51, to an outstanding bracket 52 secured to the track and the inner endterminating in'an eye 53. v c I r I a The rear end of the track carries a stop 54 engageable with the inner end of the, arm til and the arm is held normally pressed agalnst the stop by a coiled spring 51 connecting the arm to the bracket. The eye is normally held by the latter spring and stop that willreceive the pointed rear end of the love 49 as "the same moves backwardly with th container. n According to the above arrangemen", 't will be apparent thatJwhen thepointed ends of the levers have entered the eyes in the rear movement of the container, the stops will engage the eyes and in the furtherrearward movement ofthe container, the levir arms 51 will be compelled to swing rearwai lly and'out'wardly around their pivot pants 51 andlas they swing, will cause the out swinging of the levers 49 and the consequent out swinging of the gates through the rods 50'; the final out swung position of one of 2' he starts to move forwardly. In the forward movement of; the container, the gates gradu-- all 1 closelinmthe arms 51 swin in back to their normal position as shown in Figure 2 and the pointed ends of he levers 49 withdrawing from the eyes and then riding ahead in contact with the inner faces of the tracks horizontally disposed, relatively long bars and, which have their forward ends connected by a vertical bar 55*.

An upper angularly disposed brace bar 56 extends between the upper end of the bar 55 and the upper part of the frame work and two angularly disposed horizontal brace bars 57 and 57' extend also forwardly from the container frame work and have their converging forward ends permanently fastened to the upper end of the bar 55*. These brace bars amply support and reinforce the forward ends of the bars 55 and 55 and it will be observed that all the latter bars move with the container. The bars 55 and 55 support opposing, horizontal lying, spaced, upper and lower rack bars 58 and 58 and it will be here observed that the forward end of the lower rack bar extends in advance of the forward end of the upper rack bar and that the rear end of the upper rack bar extends rearwardly beyond the rear end of the lower rack bar.

The main frame of the machine carries forwardly and more or less centrally thereof, upper and lower rollers 59 and 59, the roller 59 continuously riding the upper side of the car 55 while the roller 59 continuously rides the under side of the bar 55, the bars 55' and 55 forming tracks for these rollers as well as supports for the rack bars. From the above, it will be apparent that the weight of the cylindrical container is carried by the rollers 43 and 43 operating on the tracks 44 and 44 and it is prevented from tilting as it moves backwardly and forwardly by the rollers 59 and 59 operating on the forward tracks or bars 55 and 55.

To the shaft, I secure permanently a driving gear wheel 60 which is positioned be tween the rack bars and has the teeth thereof at all times clear of the rack bars. The shaft carries also a pair of rearwardly extending arms 61 and 61 which are rotatably mounted on the shaft and span the gear wheel and have their rear ends supporting a short shaft 62 on which I mount a further gear wheel 63 continuously meshing with the gear wheel 60 and positioned between the rack bars.

The gear wheel 63 is utilized for shifting the container by engagament with one or other of the rack bars as it will be apparent that one by lifting the gear wheel 63 can oass it into engagement with the upper rack bar and by lowering it can pass it into engagement with the lower rack bar. The raising and lowering of the gear wheel 63 is controlled by the attendant from the seat 15 in the following way.

To the rear ends of the arms 61 and 61, I pivotally connect the lower ends of up wardly extending bars 64 and 64 which have their upper ends pivotally connected to similar cranks 65 and 65 extending rearwardly from the shaft 27 hereinbefore mentioned which shaft it will also be remembered controls the movement of the table 18 through the clutch 25, the arrangement being such that during the interval that the container is moving rearwardly, the table is not rotating as the clutch 25 is disengaged coincident with the up movement of the gear 63 into contact with the rack 58. It will be observed that the instant the gear 63 engages the rear end of the rack bar 58 (see Figure the container will start moving rearwardly and will continue to move rear-wardly till said gear runs off the front end of the said rack bar at which time the container will stop at its rearmost position, the table being inert during the r ar movement of the container.

When the attendant desires to return the container to its original forward position, he will shift the lever 29 in a direction to swing; the gear 63 into contact with the underlying extended end of the rack bar 58 at which time, the clutch 25 will be engaged and the table will commence to rotate.

As soon as the said gear and latter rack bar are in engagement, the container moves ahead and will continue until the gear 63 runs off the rear end of the rack bar 58 and when this occurs the container is forward in its original receiving position and the clutch 25 remains in gear so that the table continues to rotate as the stack is being built in the container.

The forward end of the main frame is supported by a comparatively heavy forwardly extending stub tongue 66 supported by a for ward truck 67, the stub tongue being braced by an angularly disposed beam 68 and the machine is drawn from the truck by a tractor or draft animals.

The machine is utilized in conjunction with a further harvesting machine somewhat (if the type of a binding machine which is indicated generally by the reference numeral 69, such latter machine cutting the standing grain on the field and delivering it to the elevator of the herein described machine. The inner side of the machine for cutting the grain is located at the bull wheel side of my machine and the inner side of the grain cutting machine is adjustably supported so that it can be raised and lowered and to this end, I provide my machine in a location adjoining the drivers seat with two levers 70 and 70, the lever 70 having a pulling line 71 fastened thereto which pulling line extends forwardly over a guide pulley 71 located at the Ill forward inner corner of my machine and has the lower end of the line fastened to the forward inner corner of the cutting machine frame. The lever 7 O carries a crank '7 2 which is connected pivotally to a downwardly extending link 72' pivotally attached to the rear inner corner of the cutting machine frame.

According to this arrangement by manipulating the latter levers one can raise or lower the inner side of the cutting machine frame and accordingly adjust it in respect to the inclined elevator 73 supported by the main frame ofmy machine at the side next the cutting machine. This elevator, the structural details of which are not herein described, is designed to elevate the cut grain and discharge the same into a hopper 7 4 located above the container when the container is in its forward position. The details of thehopper are not herein described and in connection with the present disclosure, it is sufficient to understand that the hopper is provided with bottom doors which can be controlled by the attendant to discharge the grain and also direct the grain when discharging either forwardly or rearwardly in regard to the container. I

It is desirable to pack the grain discharged into the container and to this end the packer 38 is used which packer is rotated at the same speed as the table and rolls on top of the grain in the container, the packer being a floating one so that it can'rise to accommodate the gradual filling of the container with the grain. The packer 38 also re-.

mains at all times with the container and ac-' ,cordingly I provide a driving arrangement which automatically becomes disengaged when the container starts moving rearwardly and subsequently becomes engaged when the container returns to its original forward position.

The packer38 is of a frusto-conical shape as best shown in Figure 2 and it is positioned with the large end outward and the packer shaft 38 is contained in a vertical plane radial to the container and protrudes through the'side of the container between a pair of vertically disposed guide bars 75 and 7 5' carried by the container frame work, these guiding the shaft in its up and down movement. A stop block 7 5" extends between the guide bars 75 and 75 and limits the down l swung position of the shaft 38 in which position the under side of the packer 38 is contained substantially in the horizontal plane and is well clear of the underlying table. The packer is provided with lengthwise extending cleats 76 in the form of applied angle llOIlS.

The forward end of the shaft 38 isiconnected by a universal joint of well. known type 77 to the rear end of a short shaft 77 mounted in suitable bearings carried by the lar and slightly pointed as shown and the forward end of which is supplied with a bevel gear 7 9*, the bevel gear being continuously in mesh with a bevel gear'80 locatedat the upper end of a vertically disposed shaft 80 carried by the machine frame and having the lower end thereof fitted with a bevel gear s 80* engaging continuously with a bevel gear 80 secured to the shaft 10.-

According to o the above arrangement, it will be apparent that when the shaft. 10 is driven, the shaft 79 willbe rotated and that if the rear end of the latter shaft is entered in the hole 7 7 of the shaft 7 7, the packer 38 will be driven.

Such a condition exists when the container is in its normal forward position. On the other hand, when the container is moved back to discharge the contained stack, the shaft 7 7 moves away from the shaft79 so that the packer stops rotating and does not again start to rotate until the container is returned to its. original position'at which time, the rear end of the shaft 7 9 re-enters the hole 77 It will be here noted that the universal joint 77 permits the packer 38 to rise and fall while it is being driven. 7 7

It is also very desirable to tuck the side of the stack "being formed in the container-to interknit thestraw and this is accomplished by the tucker 39 hereinbefore mentioned and which is constructed in detail as now described. r

The container frame worksupports rotatably a vertically disposed shaft 81 and this shaft carries a plurality of curved fingers 81' formed in pairs as best shown in Figure-8 and suitably bolted to the shaft. The pairs of fingers extend outwardly from the shaft and are placed 90 apart and the body 31 of the container is provided with a plurality of horizontally disposed slots 82 through which the rotating fingers enter the container in th manner best shown in Figure 2.

The frame work of the container supports rotatably a horizontally disposed forwardly extending shaft 83 which has the rear end thereof provided with a bevel gear 83 continuously in mesh with a bevel gear 83* secured'to the vertical shaft 81. The shaft 83 has the forward end thereof provided with a non-circular opening identical to the opensame manner as the shaft 79 and the arrangement of the parts is such that when the container is in its forward position, the shaft 23 drives shaft 83 and consequently the tucker 39 and such that when the container moves back, the rear end of the shaft 23' escapes from the hole in the forward end of the shaft 83 so that the tucker 39 remains inert during the backward and subsequent forward move ment of the container.

The elevator driving shaft 84 is fitted with a bevel pinion 8 f continuously in mesh with a bevel pinion 85 located at the upper end of an inclined shaft 85 rotatably carried by the machine frame and the lower end of the shaft is supplied with av bevel pinion 86 which is continuously in mesh witha bevel gear 86 located more or less centrally on a. horizontally disposed countershaft 86 carried by the fore part of the main frame, The countershaft has the front end thereof fitted with a bevel gear 87 which meshes continuously with a bevel gear 87 secured to the main shaft 10, the result being that the elevator is driven as long as the shaft 10 is rotated. The rear end of the shaft 86 is supplied with admin wheel 88 which is connected by a chain 88 to a chain wheel 89 secured on the forward end of a rearwardly extending shaft 89 suitably carried by the inner side of the main frame. The chain wheel is provided with an eccentric pin 90 to which is connected pivota'lly a pitman 90 extending towards the cutting machine 69 and utilized for driving the cutting knives 69 of such machine. The rearend of the shaft 89 is provided with a bevel gear 91 which meshes continuously with a bevelpinion 91 located at the inner end of a relatively short shaft 92 carried by the rear inner corner of the main frame and this shaft is utilized to drive the canvas 69 of the grain cutting machine, the connections being shown in Figure 2 but not described in detail. a

From the above description, it willbe seen that all the various moving parts are driven by the shaft 10 and that the shaft is operated by the bull or master wheel 2, the clutch 11 being supplied so that when out the machine can move over the ground with all the moving parts described inert. This is valuable when the machine is being transported from place to place.

In order to better understand the machine, I will now describe the manner in which it operates, assuming that it is moving over the field with the grain cutting machine, with the clutch 11 engaged, the gear wheel 63 in the position shown in Figure 3 and the clutch 25 engaged. At such time, the elevafor will be in operation and delivering the cut grain from the cutting machine to the 1 hopper (4e and the cut gram Wlll be d1schargmg from the hopper ly gravity into the container which is in its forward position with the gates closed. Tlhetable will also at such time be rotating and the packer and tucker will be working.

The hopper is located in respect to the underlying cylindrical container that the grain is deposited in the container with the heads located centrally of the container and the butts disposed adjacent the sides of the container and here it is to be noted that the standing grain cut by the cutting machine falls with the heads to the rear of the canvas 69 thereof and will be carried up the elevator with the heads to the rear so that if the hopper be pr perly positioned in respect to the cylindrical container, the heads will all fall approximately in the central area of the container. As the grain is falling, the table is rotating so that the grain is laid in the container in a spiralling manner, heads in and butts out.

The grain in the lowermost part of the container not initially packed by the packer 38 as such is not necessary due to the fact that as the height of the stack increases, the weight of the upper part of the stack will serve to press down the grain in the base thereof. As the height of the stack in creases, however, t e packer 38 comes into commission and presses down on the top of the building stack, it being remembered that the said packer can move up to accommodate the gradual increasingheight of the stack being formed. It will also be noted that the cone shaped formation of this packer will give the completed stack a conically shaped top which is very desirable the stack on tile field will shed rain.

During the interval that the stack is being built, the tucker 39 is also working to aid ti e table in rotating the stack within the cylindrical container and as the tucker 39 is rotated slightly faster than the table, the fingers have the ifect of tucking the side of the stack to intertwine the butts of the grain so that when the stack is subsequently deposited on the field, it will be firm and there is ver little possibility of wind blowing the grain away or upsetting the stack. The fact that the heads of the grain are located centrally of the stack is also quite desirable. a

When the operator considers that the stack satisfactorily built in the container, he pulls the lever 29 in a direction wnieh will ongage the gear wheel 63 with the raclr which will start the container moving back and which also disengages the clutch. 25 so that the table stops rotating. A the con- 1L; tainer starts to more back, it is initially raised slightly by the ofl'ets id to permit the bottom of the container to clear over the cleats 18 and coincic ent with the in t al bacl: movement of the container, the pa rs 38 and 35) cease operating as the shaft 77 moves away from shaft 79 and the shaft 83 moves away from shaft 23.

fan 1 cal the springs and the pressure bars 47.

planted stack to clear.

During the time that the stack is being formed, the gates are positively held shut by As the container moves back on the tracks, the pressure bars escape from the guide bars 48 and the pointed ends of the levers 49 enter the eyes 53. The gates are then gradually opened moving out to a position to allow the At this time, the gear wheel 63 has reached the forward end of the rack bar 58 and runs off the same with the result that the container stops in its rearmost into engagement with the then underlying.

forward end of the rack bar 58.'

\Vhen this occurs, the container moves ahead to its original positiomthegates beingclosed automatically and without slamming-and held closed by the combined action of the bars 4-7 and the springs 50. The latter movement of the lever 29 also re-engages the clutch 25 so that the table starts to rotate when the container starts its forward movement and as the container reaches its forward position, the shafts 7 9 and 7 7 re-engage as'do also'the shafts 23" and 83, such resulting in the driving of the packer 38 and tucker 39. The elevator is operating continuously while the machine is working and the capacity of the hopper is such that t will hold suflici'ent n to permit of the depositing of thestaclr.

"When the machine is being moved from place toplace, the attendant will manipulate the lever 13' to disengage theclntch ll'and at such time, the chain wheel 9 will rotate idlyon the shaft 10 which remains stationary. Accordingly all parts driven by the latter shaft will be inert.
